Essential Clauses for Arizona Roommate Agreements

Sharing your home with a roommate in Arizona can reduce costs and make city living affordable. But to avoid misunderstandings later, it’s important that all roommates are on the same page. A clear roommate agreement can help establish each person’s rights and responsibilities under Arizona law, providing everyone with peace of mind in a shared space.

Why Create a Roommate Agreement in Arizona?

While a lease binds all tenants to the landlord, a roommate agreement is a contract between roommates covering everything from rent splits to house rules. In Arizona, a written agreement is not legally required, but it can help resolve disputes—from unpaid bills to cleaning duties—without involving the landlord or risking legal trouble. Roommate agreements are especially helpful when only one tenant signs the main lease but sublets, or if all roommates are listed as co-tenants.

Must-Have Clauses for Your Arizona Roommate Agreement

Including these clauses will set clear expectations and help avoid common pitfalls for shared housing situations in Arizona.

  • Names and Contact Information: List the full names and phone numbers of all roommates sharing the rental.
  • Rent Payment Details: Specify each roommate’s share of the rent, payment method, due date, and what happens if a payment is late. Make it clear who submits payment to the landlord or handles any transfers.
  • Security Deposit: Explain each roommate’s share, how the deposit is held, and the process if someone moves out early. Arizona law covers deposits in A.R.S. § 33-1321.
  • Utilities and Other Bills: List how each utility or bill is divided, who oversees payments, when they’re due, and what happens if a roommate is late or moves out.
  • House Rules and Shared Spaces: Agree on cleaning schedules, guest policies, noise guidelines, and use of shared spaces such as kitchens, laundry, and bathrooms.
  • Household Supplies: Clarify how essentials (toilet paper, soap) will be purchased and split.
  • Room Assignments and whether changes are allowed after moving in.
  • Duration and Termination: Note the lease end date or sublet period, and the steps required if a roommate wants to move out early.
  • Subletting and Replacements: Set rules for subletting or bringing in a new roommate. Arizona landlords may require written approval for changes per the Arizona Residential Landlord and Tenant Act.
  • Dispute Resolution: Decide how disputes will be handled—mediation, house meetings, or another agreed-upon method.

It’s a good idea for all roommates to sign and date the agreement, then keep a copy for reference.

Relevant Forms for Arizona Renters Sharing a Home

While there is no mandated government "Roommate Agreement" form in Arizona, you should be aware of these important tenant forms if you live with roommates:

  • Arizona Residential Lease Agreement
    Use when all roommates are signing a new lease with a landlord. Ensure every roommate’s name is included. Let’s say you and your friend plan to rent an apartment together—each should sign the lease to ensure both are legally protected.
    Find more instructions and a sample on the Arizona Industrial Commission Tenant Rights page.
  • Move-in and Move-out Inspection Checklist
    This form is not required but highly recommended. Each roommate should document the rental unit’s condition to protect your share of the security deposit. Download sample checklists from the Arizona Department of Housing.
  • Notice of Intent to Vacate
    If a roommate is moving out, written notice must often be given. For example, if you decide to leave before the lease ends, submitting a written Intent to Vacate protects you under Arizona law and ensures you’re not held responsible for future rent. You can see official guidelines on the Arizona Department of Housing site.

For more about official forms or if you need to file a complaint, visit the Arizona Department of Housing's Landlord and Tenant section.

Arizona’s Tribunals and Governing Laws

Most shared housing disputes in Arizona fall under the Arizona Residential Landlord and Tenant Act. Eviction, rent increase, or unresolved roommate issues may be handled in small claims court or the relevant Arizona Department of Housing division. The Act covers security deposits, rental responsibilities, and notice procedures. If you plan to sublet, you must still follow lease terms and may need your landlord’s consent.

Tip: Whenever possible, ensure your roommate agreement doesn’t contradict your lease or Arizona’s landlord-tenant law.

Practical Steps: What to Do When Issues Arise

If you encounter a conflict or a roommate breaks their part of the agreement, try a house meeting first. Document all communications in writing for your own protection. If you need to formally end the agreement, provide written notice and consult your main lease terms. For legal help or mediation, reach out to Arizona’s Department of Housing or local tenant resources.
